一、掌握be动词及其用法。

动词时表示动作或状态的词。表示状态的动词(动词又称为be动词)。

to be 在小学阶段有两种用法:(1)作为实义动词,am,is, are翻译成“是”的意思。(2)助动词,即用在现在进行时中,无实际意义。am, is, are是be动词在不同情况下的不同形式。它们必须和主语在人称和数上保持一致。

顺口溜:我用am,你用are,单数is,复数are。

人称

复数

第一

I am我是

We are我们是

第二

You are你是

You are你们是

第三

He/She/It is他、她、它是

They are他们、她们、它们是

二、be动词可以和主语缩写。

如:I am=I’m; you are=you’re; heis=he’s;

she is =she’s; it is=it’s; weare=we’re;

they are=they’re; Tom is= Tom’s; thatis=that’s;

what is=what’s; who are=who’re等等。但要注意:不能缩写的要特殊记忆,this is≠this’s; Yes, he is.≠Yes, he’s.
